What is new here is the detailed discussion of several important results in the classical foundations of mathematics and of the relation of logic to mathematics. As regards logical questions, the central thesis of Wittgenstein's later philosophy is well known, both from the earlier posthumous volume and from the writings of his many disciples. In the Investigations the thesis is applied to the "logic of our expressions" in everyday contexts; here he discusses in the same spirit the more specialized language (...) used in talking about the foundations of mathematics.

First published in 1967, _Writing and Difference_, a collection of Jacques Derrida's essays written between 1959 and 1966, has become a landmark of contemporary French thought. In it we find Derrida at work on his systematic deconstruction of Western metaphysics. The book's first half, which includes the celebrated essay on Descartes and Foucault, shows the development of Derrida's method of deconstruction. In these essays, Derrida demonstrates the traditional nature of some purportedly nontraditional currents of modern thought—one of his main targets (...) being the way in which "structuralism" unwittingly repeats metaphysical concepts in its use of linguistic models. The second half of the book contains some of Derrida's most compelling analyses of why and how metaphysical thinking must exclude writing from its conception of language, finally showing metaphysics to be constituted by this exclusion. These essays on Artaud, Freud, Bataille, Hegel, and Lévi-Strauss have served as introductions to Derrida's notions of writing and _différence_—the untranslatable formulation of a nonmetaphysical "concept" that does not exclude writing—for almost a generation of students of literature, philosophy, and psychoanalysis. _Writing and Difference_ reveals the unacknowledged program that makes thought itself possible. In analyzing the contradictions inherent in this program, Derrida foes on to develop new ways of thinking, reading, and writing,—new ways based on the most complete and rigorous understanding of the old ways. Scholars and students from all disciplines will find _Writing and Difference_ an excellent introduction to perhaps the most challenging of contemporary French thinkers—challenging because Derrida questions thought as we know it.

Abstract:McMahan, Nussbaum, and Johannsen have recently suggested that humans should seek to eliminate predators from the wild or avoid reintroducing them if this can be done without great harm to an ecosystem. This is because predators cause a great deal of pain to those sentient animals which are their prey. This paper will first challenge the pragmatic aspects of such a position on the global level, arguing that it would be extremely difficult if not impossible to remove predators from the (...) environment without doing great ecological harm. Because removal of predators might be considered more feasible on the micro scale this paper will go on to challenge the axiological foundations of such a view. In particular defenders of the removal of predators from the environment tend to base their position on the preferencing of the disvalue of pain over the value of life. Yet if life itself has value it can be a good even with those beings that cause pain to others. Moreover, there is a value to diverse forms of life that must also be acknowledged. An ecosystem with diverse habits and life forms exercising different ways of being has great value even if again this comes at the cost of suffering and pain to some of the creatures in it. Once these things are understood it is clear that predators should not be eliminated from the wild and indeed should be reintroduced into ecosystems where they once flourished. (shrink)

Originally published in 1988, this book discusses if moral knowledge exists, and if so, if it is similar to other forms of knowledge. This book approaches the issues from both historical and contemporary perspectives and in order to determine whether there is a real property of rightness, looks to the ethical theories of Hobbes, Hume and Kant. This historical analysis leads to a systematic comparison of three theories of the nature of ethics: realism, emotivism and coherentism. The nature of coherence (...) is explained using legal reasoning as a model. Moral reasoning is compared and contrasted with reasoning both in science and law, showing how ethics differs from science and empirical disciplines. (shrink)

The themes of the book—the value of knowledge and epistemic appraisal broadly conceived—are introduced in this chapter. The Meno problem is explained and related to the swamping problem as discussed by Jonathan Kvanvig. The stance of virtue epistemologists is outlined. This is followed by a brief discussion of the role of truth in epistemic appraisal. The remainder of the introduction summarises the contributions to the book.

There has been a rising interest in the study of Mary Wollstonecraft (1759-1797) in philosophy, political theory, literary studies and the history of political thought in recent decades. The Wollstonecraftian Mind seeks to provide a comprehensive survey of her work, not only placing it in its historical context but also exploring its contemporary significance. Comprising 38 chapters by a team of international contributors this handbook covers: the background to Wollstonecraft’s work Wollstonecraft’s major works the relationship between Wollstonecraft and other major (...) philosophers Wollstonecraftian philosophy Wollstonecraft’s legacy Essential reading for students and researchers in philosophy, Wollstonecraft’s work is central to the study of political philosophy, literature, French studies, political thought, and feminism.

In r-Dagger define t as for some p, P, F as for all p, P. Then (t, F) is closed in r-Dagger under truth-Functions and relevant implication, Which, When confined to (t, F) acts just like material 'implication.' but r-Dagger admits of many propositions other than t, F. The article also contains polemics against extensionalism and nominalism. (edited).

In her dedicated promotion of feminism and pacifism, especially during the 1930s, Vera Brittain (1893–1970) was strongly influenced by Ber­trand Russell’s writings, especially Marriage and Morals (1929) and Which Way to Peace? (1936). Both were members of the Peace Pledge Union, and she continued as a sponsor after Russell abandoned his pac­ifism soon after the beginning of the Second World War. She admired his political and social activism in the aftermath of that war, endorsing it as much as her family (...) situation allowed; and, as chairman of the Peace News board, Brittain intervened in Russell’s support when a dispute broke out between him and the editor. Although their rela­tionship was personally limited, Russell’s influence on her opinions and actions was profound. (shrink)

This collection explores the impact of Richard Dawkins as scientist, rationalist and one of the most important thinkers alive today. Specially commissioned pieces by leading figures in science, philosophy, literature, and the media, such as Daniel C. Dennett, Matt Ridley, Steven Pinker, Philip Pullman and the Bishop of Oxford, highlight the breadth and range of Dawkins' influence on modern science and culture, from the gene's eye view of evolution to his energetic engagement in public debates on science, rationalism, and religion. (...) The volume includes personal reminiscences and critical debate as well as accessible discussions of science – it provides a stimulating tribute to a remarkable intellectual. (shrink)

This ambitious and sweeping book presents a powerful argument against moral relativism and in favor of the objectivity of a theory of democratic individuality. Unlike much recent work in this field, the book does not simply adumbrate such a view. Rather, it develops the parallels between various versions of scientific and moral realism, and then reinterprets the history and internal logic of democratic theory, maintaining, for example, that the abolition of slavery represents genuine moral progress. The book also recasts the (...) clashes between Marxist and Weberian, radical and liberal sociologies in the light of these moral claims, and sketches the institutions of a radical democracy.

It is widely accepted that stressful conditions can facilitate evolutionary change. The mechanisms elucidated thus far accomplish this with a generic increase in heritable variation that facilitates more rapid adaptive evolution, often via plastic modifications of existing characters. Through scrutiny of different meanings of stress in biological research, and an explicit recognition that stressors must be characterized relative to their effect on capacities for maintaining functional integrity, we distinguish between: (1) previously identified stress-responsive mechanisms that facilitate evolution by maintaining an (...) adaptive fit with the environment, and (2) the co-option of stress-responsive mechanisms that are specific to stressors leading to the origin of novelties via compensation. Unlike standard accounts of gene co-option that identify component sources of evolutionary change, our model documents the cost-benefit trade-offs and thereby explains how one mechanism—an immediate response to acute stress—is transformed evolutionarily into another—routine protection from recurring stressors. We illustrate our argument with examples from cell type origination as well as processes and structures at higher levels of organization. These examples suggest a general principle of evolutionary origination based on the capacity to switch between regulatory states related to reproduction and proliferation versus survival and differentiation.
